Not as cool this week—and definitely wetter
With a predominantly southwesterly flow aloft, this week portends to be a bit warmer than last week. Sunny skies and southwest winds will boost temperatures into the mid-50s Sunday afternoon.
Chicagoans will be in the southern portion of cool high pressure on Monday and Tuesday, with easterly winds holding highs in the low 50s.
However, low pressure is projected to develop in the central Plains, bringing us a period of cloudiness and rain. The main show is forecast to occur on Halloween, with the center of low pressure intensifying as it moves northeast.
Later Wednesday into Thursday, showers and thunderstorm downpours will develop ahead of an approaching cold front.
Showers should end early Friday as cooler, drier high pressure follows into the Midwest.
